Sync VEX/LICENSE.GPL with top-level COPYING file. We used 3 different
addresses for writing to the FSF to receive a copy of the GPL. Replace
all different variants with an URL <http://www.gnu.org/licenses/>.
The following files might still have some slightly different (L)GPL
copyright notice because they were derived from other programs:
- files under coregrind/m_demangle which come from libiberty:
cplus-dem.c, d-demangle.c, demangle.h, rust-demangle.c,
safe-ctype.c and safe-ctype.h
- coregrind/m_demangle/dyn-string.[hc] derived from GCC.
- coregrind/m_demangle/ansidecl.h derived from glibc.
- VEX files for FMA detived from glibc:
host_generic_maddf.h and host_generic_maddf.c
- files under coregrin/m_debuginfo derived from LZO:
lzoconf.h, lzodefs.h, minilzo-inl.c and minilzo.h
- files under coregrind/m_gdbserver detived from GDB:
gdb/signals.h, inferiors.c, regcache.c, regcache.h,
regdef.h, remote-utils.c, server.c, server.h, signals.c,
target.c, target.h and utils.c
Plus the following test files:
- none/tests/ppc32/testVMX.c derived from testVMX.
- ppc tests derived from QEMU: jm-insns.c, ppc64_helpers.h
and test_isa_3_0.c
- tests derived from bzip2 (with embedded GPL text in code):
hackedbz2.c, origin5-bz2.c, varinfo6.c

To detect calls and returns, Callgrind's heuristic
starts with using the jumpkind got from VEX for
a control flow change instruction. However, for
side exits, it always assumed a (conditional) jump,
which holds true for x86, but e.g. not for ARM.
This fixes Callgrind to use the jumpkind found
by VEX for all exits, which should help making
Callgrind work for ARM. It also moves the check
whether a boring jump is actually a fall-through
to instrumentation time. This changes (fixes) the
result for indirect jumps to the next instruction,
which should not be classified as fall-through
(anyway, this case is probably very rare).
This patch introduces an own enum for jump kinds
in Callgrind. This is less confusing than misusing
the VEX jump kind type, as Callgrinds wants
to distinguish BB fall-throughs from real jumps
(which both are Ijk_Boring in VEX).
Also, setup_bbcc now stores separately whether the
jump kind is conditional or not.

When unwinding needs to be done because the stack pointer is reset
(e.g. by a longjmp), it makes no sense to interprete the control
flow change as call, but should be seen as a return.
This indirectly fixes bug 246152. Unwinding potentially changes the
exec state, which is unique for threads, but also for signal handlers.
E.g. this is true for a longjmp out of a signal handler. Exec state
changes modify members of struct CLG_(current_state), such as
CLG_(current_state).bbcc and CLG_(current_state).jmps_passed, which
are backed in CLG_(setup_bbcc)() by last_bbcc and passed, respectivly.
On a exec state change, these local vars go out of sync, and lead
to invalid data passed to CLG_(push_call_stack)() for handling a call,
which triggered data corruption, and the symptoms seen in bug 246152.
As in the given situation, there is no call anymore, there is no call
into CLG_(push_call_stack)(), and the corruption (or since last commit
the failed assertion) is not triggered any more.

relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.
The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.
